30% = 0.3

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.

Solution:

To write percent to decimal, divide the number by 100.

$30\%=\frac{30}{100}

       $=\frac{30\div10}{100\div 10}

       $=\frac{3}{10}

       = 0.3

30% = 0.3

Average use of water each day = 90 gallons

30\%  \ \text{of} \ 90=0.3 \times 90

                = 27

Since 30% of 90 is 27, the average person uses approximately 27 gallons of water outdoors per day.
